Ni irihe tandukaniro riri hagati yumye-ivanze na wet-ivanze ya shoti?

Shotcrete ni ibikoresho byubwubatsi bikoreshwa muburyo bwo gukora ibintu nkurukuta, amagorofa, nigisenge.Nibikoresho byinshi cyane bishobora gukoreshwa muburyo butandukanye, harimo imirongo ya tunnel, ibidendezi byo koga, hamwe no kugumana inkuta.Hariho uburyo bubiri bwingenzi bwo gukoresha amafuti: gukama-kuvanga no kuvanga.Mugihe ubwo buryo bwombi burimo gutera beto cyangwa minisiteri hejuru ukoresheje igikoresho cya pneumatike, hari itandukaniro rikomeye muburyo ibikoresho byateguwe kandi bigashyirwa mubikorwa.Muri iki kiganiro, tuzaganira ku itandukaniro riri hagati yumye-ivanze na wet-ivanze ya shoti.

Kuma-kuvanga Shotcrete:

Kuma-kuvanga ibishishwa byumye, bizwi kandi nka gunite, nuburyo bwo gutera beto yumye cyangwa minisiteri hejuru hanyuma ukongeramo amazi kuri nozzle.Ibikoresho byumye byabanje kuvangwa hanyuma bipakirwa muri hopper, bigaburira imvange mumashini ya beto.Imashini ikoresha umwuka wifunitse kugirango itere ibikoresho byumye binyuze muri hose, yerekeza hejuru yintego.Kuri nozzle, amazi yongewe kubintu byumye, bikora sima kandi bikemerera guhuza hejuru.

Imwe mu nyungu zingenzi zo gukama-kuvanga shoti ni uko itanga uburyo bunini bwo kugenzura igishushanyo mbonera.Kuberako ibikoresho byumye byabanje kuvangwa, kuvanga birashobora guhinduka kugirango byuzuze ibisabwa byingufu, imbaraga, nigihe cyo gushyiraho.Ibi bituma ihitamo neza kubikorwa byihariye aho bisabwa urwego rwo hejuru rwibisobanuro.

Iyindi nyungu ya firime yumye-ivanze ni uko ishobora gukoreshwa muburyo bworoshye kuruta kuvanga-kuvanga.Ibi bituma uhitamo neza kubisabwa aho uburemere buteye impungenge, nko kumuraro wikiraro cyangwa mubindi bihe aho bikenewe ibikoresho byoroheje.

Ariko, gukama-kuvanga amafuti nayo afite ibibi.Kuberako ibikoresho byumye bitwarwa numwuka uhumanye, hashobora kubaho umubare munini wo kwisubiraho cyangwa kurenza urugero, bishobora gutera akazi keza kandi bishobora no kuvamo ibintu byangiritse.Byongeye kandi, kubera ko amazi yongewe kuri nozzle, hashobora kubaho itandukaniro mubirimo byamazi, bishobora kugira ingaruka kumbaraga no guhuza ibicuruzwa byanyuma.

Kuvanga-Shotcrete:

Kuvanga ibishishwa bitose ni uburyo bwo gutera beto cyangwa minisiteri hejuru yubutaka burimo kubanza kuvanga ibikoresho namazi mbere yuko bishyirwa mumashini ya firime.Ibikoresho bitose noneho bisunikwa mumashanyarazi hanyuma bigaterwa hejuru yintego ukoresheje umwuka wugarije.Kuberako ibikoresho byabanje kuvangwa namazi, bisaba umuvuduko muke wumwuka kugirango ubisunike unyuze muri hose kuruta byumye-bivanze.

Imwe mu nyungu zingenzi za wet-mix-shotcrete ni uko itanga umusaruro muke cyangwa kurenza urugero kuruta kwumisha-kuvanga.Kuberako ibikoresho byabanje kuvangwa namazi, bifite umuvuduko muke iyo bisohotse, bigabanya ubwinshi bwibintu bisubira inyuma.Ibi bivamo ibidukikije bisukuye hamwe nibikoresho bidasesagura.

Iyindi nyungu ya shitingi itose-ivanze ni uko itanga ibicuruzwa bihamye kandi bihuje kuruta ibishishwa byumye.Kuberako kuvanga byabanje kuvangwa namazi, habaho itandukaniro rito mubirimo byamazi, bishobora kuvamo imbaraga zingana kandi zihamye.

Ariko, wet-mix-shotcrete nayo ifite ibibi.Kuberako ibikoresho byabanje kuvangwa namazi, ntagenzura rito kubishushanyo mbonera kuruta hamwe na firime-yumye.Byongeye kandi, ibishishwa bivanze-bisaba ibikoresho byinshi kandi birashobora kuba bihenze kuruta ibyuma-bivanze.Hanyuma, kubera ko ibishishwa bivanze bivanze bifite amazi menshi, birashobora gufata igihe kirekire kugirango bikire kandi birashobora kwibasirwa no gucika no kugabanuka.

Umwanzuro:

Muncamake, byombi byumye-kuvanga no kuvanga-shitingi ifite ibyiza byayo nibibi.
